Abstract
An endoscope cover system endoscope to be used in an endoscope inspection including an endoscope having an elongate inserted part provided with a curvable curving part and an operating part provided with a curving operating knob curving operating the curving part and a channeled endoscope cover having an inserted part cover provided with an endoscope inserting channel through which the inserted part is inserted and such fluid tube path through which a fluid flows as an air feeding tube path so that, when the curving part is curved close to the maximum curvature angle in the maximum curvature angle direction by operating the curving operating knob, the fluid tube path within the inserted part cover will be curved and twisted to move outside in the maximum curvature angle direction.
